Boot and root should be ok, but misc is probably causing problems with file managers querying fstab and hal.

Must be something like that - if I su and umount it, both icons go away. Then I 'mount -a' and only one comes back. But if I log out and log back in, they both come back. Must a new "feature" of gnome 2.20.0....

Heh, heh - I meant "feature" as in the infamous Bill Gates interview with the German technology magazine, wherein he claimed that Windows has no bugs, only features that people do not understand. (You can't make this stuff up....)
The most interesting part to me is that the disk in question is a fixed drive in the case. On my CentOS boxes and laptops, these NEVER show up on the desktop (why would they?), only the removable media.

If it is truly a fixed drive, then I would suggest a look at the logs (dmesg and/or messages) to get it "identity" and then look at udev configuration scripts. IIUC, udev is assigned the task of identifying and classifying stuff correctly. Everything else at "higher" levels of abstraction would depend on those results.
I did a locate on udev and some promising things popped up.
/etc/udev /etc/sysconfig/modules/udev-stw.modules /etc/udev/devices /etc/udev/makedev.d /etc/udev/rules.d /etc/udev/udev.conf
Plus there's a bunch of docs about it up in /usr/share/doc/udev-095, including overview and writing-udev-rules. "man -k udev" offers some potential help too.
I hope there's an answer hidden in there somewhere.

I believe the problem is simple really.
fstab has the device listed as LABEL=misc, and HAL reports it as /dev/sdX, the Gnome file manager sees these as 2 separate devices and presents them as such.
Find a way to have Gnome stop scanning the fstab file and have it rely completely on HAL, or have HAL ignore all devices listed in fstab.

Actually, I used tune2fs earlier to delete the volume label and the entry in fstab now lists the device directly.
Find a way to have Gnome stop scanning the fstab file and have it rely completely on HAL, or have HAL ignore all devices listed in fstab.
I'll look into this one.

If the "misc" is getting automounted, that would be a problem. But wasn't the "noauto" option tried (I can't remember)?

No, I want it automounted. I just don't want it to show up twice on my desktop.
I suppose I could just delete the file from my Desktop folder, but I'm not sure if that does anything detrimental or what....

You mean regardless of if desktop is started up? In that case, it sounds like System->Preferences->Removable Drives and Media settings need changing to *not* mount when hot-plugged.

Repeating is not an issue. Long threads promote forgetfulness. But I didn't forget. I'm just hazarding a guess that whatever the root cause is, changing those settings might get rid of the extra icon. That, in turn, gives a hint that might be useful. If it doesn't fix it, it also provides some help by eliminating some things... I hope.
I'm still hoping that the scan of the dmesg or messages log, in conjunction with a look a udev stuff might reveal the cause.
The settings suggestion was just a stab at getting rid of the icon, which was your stated goal.

I wonder if anyone can duplicate the problem by creating a partition and having it mounted in fstab by volume label and see if it appears twice.
If you list it in fstab by /dev/sdXX and HAL announces it as /dev/sdXX then it will only appear once, but if it is listed in fstab as LABEL=XXXX and HAL announces it as /dev/sdXX then it would be listed as twice.
I believe /boot, /, LABEL=boot and LABEL=root, are typically ignored either in Gnome or HAL or both, so those won't dup.

Not quite the same, but I've a USB drive that I plugged in after removing "noauto" from the fstab entry.
$ grep 4 /etc/fstab LABEL=BkUp_4_5 /media/sdc1 ext2 defaults,noatime 0 0
Got a nice little message telling me (in Gnome desktop) that I wasn't priveleged to mount it. That's as I would expect since I was already logged in at my desktop. Mount showed it mounted.
$ mount /dev/sdc1 on /media/sdc1 type ext2 (rw,noatime)
Now I'll reboot and see what happens.
Rebooted. Prior to entering "telinit 5", did a "mount" and it was mounted. After logging onto graphical desktop, one icon on the desktop. As expected.
I'm led back to the conclusion that there is some oddity about the device definitions on Mark's problematic unit.

Not as far as I can tell. From dmesg:

and
SELinux: initialized (dev sdc1, type ext2), uses xattr
From messages:

Nothing of interest in /var/log/gdm/:0.log.
I believe /boot, /, LABEL=boot and LABEL=root, are typically ignored either in Gnome or HAL or both, so those won't dup.
That would be another good test.

No icon on the desktop.
BTW. On the previous test, I could not umount the device from the desktop. That would be because it was mounted prior to GUI instantiation and so the GUI user was not the "owner" I guess.

BTW. Determination of device type/class is contained within the HAL/udev data bases (script, configs, hardware lists, ...). If your device is not there, or is there erroneously identified, ISTM that it could cause the system to believe it was removable media.
